I suggest one way to go might be:
Set up a 500cc TT Class for fourstroke twins and singles of capacity less than 500cc. The class should cater for three grades (based on machine and rider) 'A,B, and C'. The three grades should all run together in the same events, but separated by 5 seconds. Normal trophies, but a certificate for the winner in each grade.
A Grade could include any production racer or replica, any bike with five or six speed box, and riders who are A Grade in normal competition (moderns).
B Grade could include any drastically modifed machine with only a four speed box, trick frame etc would be allowed, and riders who are B Grade in normal competition.
C Grade could cater for near standard road machines. No five speed boxes allowed. No trick frames etc. (In this class also any 350cc machines of any type as long as they are twin or single four stroke).
The class should include machines of P3,P4,P5 and P6, as long as they are single or twin four strokes of less than 500cc capacity. Only proviso would be that every machine must be fully eligible for at least one 'period', i.e. no alcohol in post 1972 machines. No discs on P3 machines. No rear discs on P4 machines (except Seeley). No twin spot calipers on P4 or P5 machines.

I believe the way to start is to formulate the CLASS RULES (see above), then get someone to sponsor it.

In races, you could start the C graders off first, followed by B Graders, then A graders, at 5 seconds between the groups.
In effect your rotten old Indian Enfields would get away first with a few near standard Brit bikes and all the 350s. Next would be P4, P5, P6 and trick P3 with four speed boxes, and/or B grade riders. Followed by the Andy Molnar Manxes, and other production racers such as normal Manxes and G50s and goldies, and/or A grade riders.
I hate to suggest this handicapping method but in this situation the speed differentials wouldn't be that great.

Alan, how would we work with grading within the Historic Section, has it operated before?

John, In the sixties and seventies, all 'modern' races were graded. If you won a couple of C grade races you were likely to be bumped up to B Grade. If you were a top rider you would get to A grade. I think its essentially the same today in modern racing.

What I'm suggesting is a twofold approach - rider and machine.

One aspect is rider ability. If a rider is an A grader he should start of with an A Graders handicap, similarly for B Graders (B Grade handicap). So for historic races these grades should stand, if a rider is ever grade A grade, he is A grade until the grading committeee downgrades him.

Another way of putting people into A grade or B grade could also be based on their machines. There are some machines which are pretty much standard. If a C grader turns up with an indian enfield, he can start off from the front of the grid ( a few seconds ahead). If he turns up with a P4 with a trick frame and a fourspeed box he automatically starts with a B grade handicap (a few seconds behind) If he turns up with the Ray Berry Manx, he gets an A graders handicap (a few more seconds behind).

You only need three groups to run this handicap system A,B, and C. Separate them by a few seconds with C grade leading.
As far as I know there have never been separate A,B, and C grade events in historic races, mainly because the numbers just weren't there. I don't think anyone has ever thought of using the grades for handicapping.

The grades:
A grade - A grade riders (as graded by the grading committee)and riders riding production racers, or bikes with five or six speed boxes. Any two stroke machines automatically in A grade.
B Grade - B Grade riders (as graded by the grading committee) and riders riding P4 (or later) bikes with trick frames. Only bikes with four or less gears allowed.
C Grade - C Grade riders (as graded by the grading committee) riding relatively standard P3 and earlier bikes. All 350s (except two strokes) with riders of any grade (as graded by the grading Committee)
 

 
Is your machine authentic or merely eligible?
